CHANNELING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 458,331, dated August 25, 1891.'

Application filed March l0, 1891.

Be it known that I, HENRY HERBERT AR- NOLD, of Rockland, county of Plymouth,

VState of Massachusetts, have invented an Improvement in Channeling-Machines for Boots and Shoes, of which the following description, in connection With the accompanying drawings, is aspecication, like letters and figures on the drawings representing likeparts.

It has heretofore been common to channel the soles of boots and shoes before applying or securing them to the boot or shoe, and when so channeled a pattern-plate is used, or the channel-cutting tool is guided by the edge of the sole. The channelor slit which is cut rarelyexactly conforms to the shape of the boot or shoe to which it is to be secured, and hence such channeled sole is objection- In order to cut the channel so that it shall exactly conform to the shape of theinished boot or shoe, I iind it is most desirable to employ the last as the guide, and with this object in view I have devised a channelingmachine which comprehends the employment of a channel-cutting blade mounted on a rocking or tilted block or holder, movement of which is entirely unrestrained, said block or holder` aifording a bearing for the outer face of the sole while the blade cuts the channel or slit, and a gage-roll or equivalent is provided which bears upon the opposite or welt side of the sole and against the upper drawn taut over the last, so that as the boot or shoe is fed or carried forward the channel or slit which is cut will exactly conform to the shape of the last. The gage-roll or equivalent presser which bears on the welt side of the sole against the upper, drawn taut over the last, is adapted to yield. The rocking or tilting blade-holder is supported by an armor carrier, preferably adapted to oscillate or to have a movement substantially at right angles to the movement of the said blade-holder. In addition to the bearing for the sole aorded by the blade-holder, I preferably employ one or more bearing-rolls or equivalents, which are made yielding. In order to obtain the best results the channelcutting blade is located in alignment with the axis of the arm or carrier supporting it, such relation of the parts enabling the blade Serial No. 384,435. (No model.)

to occupy a proper position to cut a slit of a certain depth regardless of the position of its holder.

Figure l shows in front elevation a boot or shoe channeling machine embodying this invention; Fig. 2, an enlarged detail of the rocking or tilting channelcutting bladeholder and its supporting or carrying arm; Fig. 3, a rear side view of the parts shown in Fig. 2; Fig. et, a plan view of the parts shown in Fig. 3; Fig. 5, a right-hand end vieW ofthe parts shown in Fig. 3; Figs. 6 and 7, details of theblades or knives to be referred to.

The main frame-work comprises a baseplate A, having erected on it suitable stands wheel a7, to which is secured a crank-arm as,

said gears serving as a means for rotating the shaft a. The roll a3 receives upon it and supports the sole of the boot or shoe in a slightly-inclined position, as shown in Fig. l. The bearing-frame ci rests on a stud b', supported by a spring b3 and extended through a hole in the base A, the said spring resting a't its lower end on the bed, the upper end of the spring acting against a collar or fixed support b2 on the upper end of the stud, the tendency of the spring being to keep the stud in its elevated position. The lower end of the stud b is screw-threaded and receives upon it at a point below the base A a nut b, by which to limit the ascent of the stud and the bearing and wheel as. The spring b3 serves as a yielding support for the frame a', and adjustment is obtained by the nut b4.

The stand B has pivoted' upon it at c2 a frame c', having bearings for a shaft c, provided at one end with a pinion c3, which is engaged and rotated by the pinion a7, the said shaft having at its opposite end a toothed beveled gear c4, which engages a beveled gear c5, secured to a short inclined shaft, to which is xed a roll c6, which bears upon the upper IOO surface of the sole of the boot or shoe and against the upper drawn taut over the last.

The roll a3 and roll cG constitute feeding mechanism for the boot or shoe.

The frame c has attached to it the upper end of a rod d, the lower end of which is passed down through a hole in the base-plate A and through a spiral spring d', the threaded part of the rod receiving a nut (Z2, adjustment of the nut d2 on the rod adjusting the tension of the spring b. A lever @,pivoted to a fixed stand or support, is connected at one end with the rod d, and its other end serves as a handle by which it may be operated. By depressing the lever e the frame c may be raised to permit the entrance of the sole of the boot or shoe beneath the gage-roll c6.

An arm or carrier having a cylindrical shank or stem f4 and a curved end f has its bearings in the stand or support B', and is adapted to be freely oscillated. A block f, pivotally connected to the outer curved end f ofthe oscillating arm, has secured to it by screws 2 3 the blade or channel-cutter f2. (See Figs. 3 and 6.) The screw 3 passes through a hole in the shank of the blade and -serves as a pivot on which it may be adjusted, and the screw 2 passes through an'elongated hole in said shank, which permits the blade to be turned on its pivot. The channel-grooving tool f3, (see Figs. 3 and 7,) is also secured to the block f by means of the screw 3, which passes through an elongated hole in the shank Aof said grooving-tool, which permits vertical adjustment thereof, as well as adjustment in the arc of a circle of which the screw 3 is the center. The channel-grooving tool is located just back of the channel-cutting blade to form a groove at the bottom of the slit formed by said channel-cutting blade. The channelcutting blade and grooving-tool are located in alignment with the axis of the oscillating arm f-, so that, regardless of the position of said arm, the cutting-blade and'groovingtool will remain in substantially the same position with relation to the work, that a slit of equal depth be cut. The rear end of the arm or carrier f at the opposite end of the stand B has a circumferential groove 4, and by the side of and parallel with the arm an adjusting-screw 5 is screwed into the stand or support B, said adjusting-screw having an annular projection 6, which enters the groove 4. By turning the adjusting-screw 5 the arm f will be moved longitudinally or toward or from the roll a3, yet at the same time it does not interfere with its free oscillating motion.

The boot or shoe containing the last and having on it the outer sole which is to be channeled is presented to the machine, the gage-roll c, owing to itsinclination, following along the top or welt side of the sole'beneath the bulging portions of the last and bearing against the upper drawn taut over the last, so that said last may serve as the true guide, and as the machine is operated the channelcutting blade will cut a slit corresponding to the shape of the last and regardless of the shape and irregular surface of the sole, the latter oftentimes being the result of building up the fore part and therebyleavin g the shank of less thickness.

rlhis machine is especially adapted for welted work.

While I prefer to employ a roll, as c, adapted to act both as a feed and gage roll, yet its most essential function is its use as a gage or guide, and hence l desire it to be understood that l do not desire to confine myself to such particular construction.

I claim-- l. In a machine for channeling boots and shoes after they have been secured upon the last, a gage-roll located at the weltside of the sole, adapted to bear against the upper drawn taut over the last, combined with a channelcutting blade and a rocking or tilting holder for it, substantially as described.

2. In a machine for channeling boots and shoes after having been secured upon the last, a gage-roll at the welt side of the sole, adapted to bear against the upper drawn taut over the last, combined with a channel-cutting blade, a blade-holder having a bearingsurface for the tread-face of the sole, and an oscillating arm or carrier supporting said blade-holder with the cutting-edges of the blade in alignment with its own axis, substantially as described.

3. ln a machine for channeling boots and shoes after they have been secured upon the last, a gage-roll at the welt side of the sole, adapted to bear against the upper drawn taut over the last, combined with a channelcutting blade, a rocking or tilting bladeholder, and an oscillating arm or carrier for said blade-holder, the axis of the arm or carrier being at right angles to the movement of the blade-holder, substantially as described.

4. In a machine for channeling boots and shoes aft-er they have been secured upon the last, a gage-roll at the welt side of the sole, adapted to bear against the upper drawn taut over the last, combined with the channel-cutting blade and a channel-grooving V tool, a holder for said blade and tool, having a bearing-surface for the tread-face of the sole, and an oscillating arm or carrier to which said holder is pivoted with its axis at right angles to the axis of the oscillating arm, substantially as described.
